and .a. vault bottom lining vplate The .vault" mold 1 consists of an "outer V mold wall 7 and an inherimo'ld wall"8,;an"d

the mold during the molding operation. The 1 outer mold wantis ,m'ade in four sections :coinprising the two "elongated side members relatively at "the corners vertical angle irons 13 secured/in vertical position to the, :endedges o tthefside members,"and having, 1 xoneflange overlap the edges ot the, side members at 14-and havingthe other flange15 spaced off from" the side members so as to provideffor the entrance o fthe edges of .the end"mernloers between-the corner of'the' aniles the end, edges/0 1": the side mem- "hers. LThetop and bottom edges of the side members or walls 10: and of the end memfsor v'vallsf,are supported loy angle transit at the top secured to; the edges of 1 themateiial along the'top' of the said plates,

and 1:7 securedgto the b ottomjedg es, it being I I understood that the sides of the mold rare :made otthin; sl1eet.. steel. Theiside plates 10, 10 are also ,provided With longitudinal 10, 10 and the en'dsll. These are positioned Hill ;su'pp0 ts,.18 18 in the form of channel irons extending horizontally along the sides and flsecure cl to the'plates riveting as shown or infamy suitable manner. 1 These longitudinal supports 18'e1 itendFheyond the side plates c ateach end and hence beyond the ends of. ,thefmolld as set 'upin molding position as Figure 3 illustrating the bottom frame of haematite assented; andare 'oonnected beyfe'na the ehdslby'cross-bfars 2O infthej, form cross-bars and the eyes supports and serve to draw the'supports to gether, tightening the outside mold n as sembled position, and the transverse bars or supports 20 are provided with eyes on pins or bolts 23. in the long axis of the Vault mold, projecting outward in a horizontal direction from. the centres of the cross-bars for engagement by a hoisting hook 26 and tackle 27 for hoisting the mold at any timeand particularly for hoisting the mold when the vault has been completed in order that it may be turned over for the convenient removal of the mold parts, andto this enol,v

i. e., to facilitate turning,I have shown the 25 secured one to theupper and the other to the lower side of thelongitudinal supports 18, and the bolts 23 are preferably mounted to rotate.

Tension is also applied transversely to the outer side walls 27 by means of transverse rods 28, one above the top of the side walls and the other beneath the bottom connecting removable vertical angle irons or other suitable beams 29 at their upper and lower ends, the bolts or rods 28 being taken up by nuts 30 outside the angle irons. As shown, the angles 29 are not connected to the side walls but are held in position during molding only'by the'tension of the bolts 28 and are removed when the mold is taken down to draw the finished vault.

The bottom of the mold which is referred to more des'criptively as the bottom mold frame shown in top plan in Figure 3 and in cross-section in Figure 8, is of particular interest, having the function of assisting in holding the mold parts in assembled position, and also the function of forming the top edge of the vault which is poured in in verted position. This bottom frame, which is elongated rectangularly in accordance with the top plan of the finished vault, is

formed of wooden strips or boards 36. as

shown by the cross-section, Figure 8, preferably covered on top by a heavy straight strip of sheetsteel 37 and provided with a line of holes 38 on one side corresponding to and registering with holes 39 in the angle irons 17 at the'bottoins of the outside walls, and a line of holes 40 on the other side registering with corresponding holes in angles at the bottom edges of the inside mold'to be described.

Secured to the centre of the bottom frame and extending along each of the four sides,

is a U7-shaped form .42 which as shown consists of two longitudinal strips 43 secured to end.

the frame members 36, 37 by any suitable.

heads of which are counter-sunk therein. The channel member 45 has a longitudinal channel or depression which as shown is sel'ni-circular, this form being the -preferred form and not essential to the invention. The

member 42 forms the U-shaped rib 47 ex tending entirely around the top edge of the vault as shown in Figure 9.' The rib 47 also supports v the sealing strip 48 which is a steelband projecting above the top of the finished vault to hold sealing material; It is held between the rib 47 and the walls 7, as shown, and molded into the vault. Itis L-shaped with the flange projecting into the vault material.

The inner mold wall'8 as well as the outside mold is formedin four sections so that the inner wall maybe knocked down and removed from the inside of the vault, but these sections 50, 51, 52, 53 meet interme: diately of the side and ends instead of being joined at the corners as are the outer walls, the ditliculty incident to removing the wall sections w iich extend the full length of one side being thus'overco-me. The inner mold walls like the outer mold walls are made of sheet steel, being p'referably roundedat the corners at 54 for convenience in disengaging them from the molded material in drawing, each section 50, 51, etc. being formed of a single sheet extending from the centre of one side around the corner to the centre of one These inner walls in the preferred structure shown are'stiflened by meansof angle irons 55liaving one flange secured' to and extending along the bottom edge of the plate on the side thereof away from the mold space 59, the other flange 56 being horizontal and provided with holes 57 registering with holes 40 in the bottom tram-e member 35, 36 and secured thereto by pins 58 extending through the holes. The plate forming the inside wall 8 of the mold is stiffened at the top by means of a flange 61 which in the form of the invention shown is formed by turningover the edge. of the plate. In the structure shown these flanges are discon tinned at the: corners for convenience in bending the plate to formthe mold. preferred mannerof forming the meeting Theedges of the sections of the inner mold is illustrated in Figure 7, which is a horizontal sectionon the line 7, '7 of Figure Gbut may "be treated as taken throughany one of the mold joints. v The joint consists of angle irons 68, 64, each having a flange secured to and extending along one of the ad acent vertical edges of the mold sections, the other flange extending" outward at right angles,

of the completed cover of the vault, The flanges of the four angles 88 secured to the .four edges of the rectangular plate 85'serve to enclose an area-of dimensions equal to the corresponding dimensions of the cover. The angles '86 are, of course, placed with the uprightflanges 88 toward the interior of the enclosure, so that flush rectangular molding surfaces only arepresented within thermold, which is in the nature .of a shallow elongated rectangular pan. To form the cover portion of the tongue and grooved joint, particularlythe groove, the mold is provided with" a rib or molding 89 secured to the bot- 88 as aforesaid.

tom, plate 85 just inside the side wall 88 and spaced therefrom by a suitable interval corresponding to the spacing of the rib on the top of the vault wall, the rib or molding 89 being extended entirely around the cover mold or pan parallel to the side wall As shown, the member 89 is of semicircular cross-section or half round, as such molding is frequently described. To strengthen the mold structure the edges are reinforced by means of. angles 91 having one flange secured to the under-surface of the plate, the rivets or bolts 92 which hold the angles 86 being also passed through the angles 91. These latter angles91 have flanges 93 projecting downwardly beneath the mold at rightangles to the plate 85 and the plate is r'einforcedby cross-bars or straps 94 extending transversely across the plate on the bottomside and secured to it at intervals by rivets 95. These straps, as shown, are turned at right angles at the ends at 96, and these end'portions overlie and are riveted to" the depending flanges 93 by rivets 97, The cover mold structure is also strengthened byangular straps 99 in the corners secured to the urespective flanges 93 of the angles 91 where they meet at the corners. The angles 91 are arranged after the manner of the angles 86 in that one extends across each end to the extreme lateral edge, and that the two angles at the lateral sides terminate at each end in contact with. the surfaces of the flanges 93 of the end angles 91.

In operation the mold is first assembled as to the inside and outside walls, and the bottom frame, as shown, particularly in Figures 4, 5 and 6, all the joints described being closed and pins 41 and 58,v Figure 4, being placed in position also tie rods 77 The grid 9 and the angles 91 at each side of the grid are then placed on the latches 82 which are swung up about their pivots 83 to the.

position in which they are shown in Figure 6. The bottom plate 5, which is to line the floor of theva'ultbeing made, is then placed on the grid overlying. the flanges 61 on the upper edges of the inside walls 8 of the mold,

the edge flange 80 of the plate 5 being spaced outwardly beyond the side walls and being 1 bers referred to.

in the preferred form, as shown, turned downwardly parallel to the inside wall 8 of the mold. 7

During the operation of molding the vault,

the mold is supported on, a suitable frame or gridding 100, see Figure 1, on a dolly jack' or truck, and is placed with the opening 102, see'Figure 4, upward, and the bottom frame accomplished by reaching under the mold.

l/Vhen the latches are released, the grid 9 and the angles 81 falland may be removed when the mold is turned.

Referring now to Figure 1, the mold and its contents are hoisted several inches free of the grid or blocks 100, and it being noted that the eyes 25 are near the centres of the respective cross-bars 20 connecting the ends of the longitudinal channels 18" extendin longitudinally on each side of the mold an secured to the side plates thereof, the manner of suspending the mold makes it very easy to rotate the latter about its longitudinal horizontal axis, and the next step consist-s in thus inverting it and lowering it again on tothe blocks 100. If the grid 9 and the angle irons 81 have not already been removed, they can be removed now by throwing latches 82 and lifting out the mem- The tie rods 77 are then removed. The next step consists in'removing the nuts 30 from the cross-rods 28, releasing the angle irons 29 which hold the side plates at the centre. Next the latches.

66 are swung to vertical position. v Next the nuts 74 are removed from the bolts 73'which hold the joints 65 connecting the plates '50, 51 and 52, 53. The pins 57 holding the inside walls in position, are then withdrawn,

releasing the inside walls from the bottom frame -35. Then the edge of the plate 50 is swung inwardly until it avoids the'edge of the vplate51 and the angle iron 63 secured to said edge. The section is thereby completely released and removed from the space within the mold member, it being understood that the remaining joints 65 have been similarly released, the removal of the inside mold is completed in themanner outlined.

The outside mold is now separated" into J sections, the first step being to remove the nuts on the ends of rods 24 which connect the longitudinal channels 18, and the next to re.

move the bolts 21 Which, pass vertically wall ofthe mold, the plate alsotorminga part of the'finis'hedproduct and being adapted [to serveasa lining or floor for the bottom insidefand outside walls :Eor said mold at the "same in the opening of the inside mold.
